Proportion of HAND by APOE ε4 allele status and age

APOE ε4 allele status	Age group
	Younger*		Older**
	HAND n (%)	No HAND n (%)	HAND n (%)	No HAND n (%)
Carriers	42 (71.2)	17 (28.8)	17 (94.4)	1 (5.6)
Noncarriers	108 (75.5)	35 (24.5)	22 (56.4)	17 (43.6)

Notes:

^*χ² (1, N = 202) = 0.41, P = 0.52, odds ratio = 0.80;

^**χ² (1, N = 57) = 8.25, P = 0.004, odds ratio = 13.14; Fisher’s exact test, P = 0.005.

Abbreviations: APOE, apolipoprotein-E; HAND, human immunodeficiency virus-associated neurocognitive disorder.
